PATENT OFFICE WILLIAMP, TARRANT, SARATOGA SPRINGS, NEW YORK, ASSIGNOB- 10 TABRANT MANUFACTURING COMPANY, OF SARATOGA SPRINGS, NEW YORK, A. COBPORATION OF NEW YORK SPRAYING APPARATU S Applieation filed March 11, 1930. Serial No. 434,884.

"This invention relates to spraying ap'paratus. p

More specifically stated, the invention relates to apparatus adapted particularly for spraying asphalt'products,such as emulsifiedajsphalt although it should 'jbe understood that the invention is; not limited in; any way' to this particular use. The pressure required for sprayingsubstances ormaterials of the character specified cannot be developed by directing. pumping the solution or emulsion, as such emulsions quickly .gumv up the pump. When substances such as that speci g; lied are to be sprayed, they are usually poured into a tank and are pumped therefrom. It is diflicult to pour such substances from a barrel without spilling a considerable quantity thereof, as the emulsion foams when being oured." 20' P 1 This invention has for its salient object to provide apparatus of the. character described, so constructed and arranged that the material to be sprayed can be dispensed or discharged directly from the containersvor barrels in which it is shipped.

Another object of the invention ,is to. provide apparatus of the character described, so

constructed and arranged that the barrel containing the emulsion can be easily and quickly. placed in the apparatus and can be reinforced Fig. 1- is anelevational view of apparatus conductedin accordance with the invention;

Fig. 2 is a topplan view of the trunk or apparatus in which the' barrel is to be supported and transported; and

Fig.3 is a sectional elevation takensubstantially on line 3-3 of Fig. -1. r The'invention briefly described-consists of i a truck, preferably a wheeled truck, comprising a frame, a cradle carried by the frame and adapted to receive 'a barrel or drum, and

means for bracing or reinforcing the heads of the barrel or drum after the barrel has been placed in position inthe crad1e.- The truck frame furthermore supports mechanism, such as a pump, forfurnishing the required pressure to the emulsion or other solution from the barrel. 7 drums are commonly provided with bungs and in order to simplify the application of the discharging mechanism to the barrel, the coupling for connecting the pressure mechanism to the barrel and the discharge hose or spraying device tothe barrel, is so constructed as to fit into the threaded opening or bung hole of the barrel.

Further details of the invention will appear from the following description.

In the particular embodiment of the invention illustrated in the drawing, there is shown a truck comprising a I substantially rectangular frame 10 supported at its front end on a single wheel 11 and at itsrear end on apair' of Wheels 12. j The wheels 12. are mounted on an axle 13 which, as shown in Fig. 3, is:

curved downwardly.

A cradle frame 15 is connected at 'its sides to the sides of the rectangular frame 10 and is, provided at its rear end with an inclined crossframe member 16. A handle 17 is pivotedat 18 to the front of the truck frame and.

is held in elevated position by a pin 19.

In order to reinforce the heads of the drum or barrel 20 when the barrel has been placed in the cradle on the truck, means isprovided at each end-of the substantially rectangular frame '10 for bracing the heads of the drum. This means comprises a circular block 21 which is sec'uredto a cross frame member 221 and a slmilar block 23wh1ch is carried by a cross beam 24: which. isadjustably mounted in slots 25 formed in the side frame members of the'frame -10. Screws 26engages the beam and bytightening the screws the barrel can be rigidly held and braced between the re inforcing members 22 and 23.

In'order to-place the barrel in the cradle,

the truck is tilted upwardly about the rear axle and, if desired, the. pin'19 can be withdrawn andreplacedafter therear end of the handle 17 has been positioned above the pin. Thus the handle will hold the truck in tilted position. When the truck is tilted, the barrel can be tilted about -one edgeand the frame Such barrels or member 16 can be placed beneath the raised edge of the barrel. The barrel can then be lowered into the cradle 15. After this has been done the beam 24 will be placed in the slots 25 and the screws 26 will be turned inwardly to cause the reinforcing members 22 and 23 to tightly engage the heads of the drum or barrel. Then the barrel is lowered into the cradle it is so positioned that the bung will be disposed at the top.

. Suitable means is provided on the truck for supplying the necessary pressure required to eject the emulsion or other solution from the barrel or drum. In the drawings there is shown a pump P which may be of any desired construction and is provided with a pressure gauge G and a discharge pipe 30.

In order to facilitate the connection of the discharging apparatus to the barrel, the coupling 31 is so dimensioned as to screw into the bung hole after the bung has been removed. Handles 32 are provided on the coupling 31 to facilitate the connection of the coupling to the barrel. The pump discharge pipe 30 is connected at 33 to the coupling and air is conducted through the coupling to the barrel. A pipe 3 lis carried by the coupling and extends to a position near the bottom of the barrel. This pipe also communicates with a discharge pipe 35 to which a spray nozzle 36 is connected. A valve 37 is provided in the pipe 35 for opening and closing the passage through'the pipe.

After the barrel or drum has been placed in the cradle, as above described, the bung 1s removed and the coupling 31 is connected to the barrel. The valve 37 is then closed and the pump P is actuated to form a pressure above the liquid in the barrel. When thls pressure has been raised to the desired amount, as indicated by the gauge G, the valve 37 is opened and the emulsion will be ejected from the barrel through the discharge pipe 35 and spray nozzle 36. The pump will be actuated to maintain the pressure during the ejection or dispensing of the emulsion.

From the foregoing description it will be evident that simple, practical anl eflicient spraying apparatus has been designed and that by the use of the apparatus drums or barrels of the emulsion or solution to be sprayed can be easily and quickly mounted on the apparatus and emptied. By the use of the apparatus described, transfer of the emulsion from the barrel or tank in which it is shipped to separate pumping mechanism is eliminated.

vention is capable of modification and that I changes in the construction and in the arrangement of the various cooperating parts may be made without departing from the spirit or scope of the invention, as expressed in the following claims.

What I claim is:

1. Apparatus of the character described comprising a truck having a frame comprising side frame members and a cross frame member at one end thereof, a cradle between said side frame members adapted to support a barrel, bracing means for one end of the barrel carried by the cross frame member, a removable cross frame member carried by the other end of the side framemembers, and bracing means for the other end of the barrel carried by said removable cross frame member.
